Principle component analysis of transgenic plant physiological and biochemical traits, antioxidant enzyme activities, photosynthetic traits, yield-related variables, gene expression and salt tolerance evaluation index. Physiological and biochemical traits [green symbols, including chlorophyll (total chlorophyll), EL (electrolyte leakage), MDA (malondialdehyde), proline, SS (soluble sugar), RA (roots activity)]; antioxidant enzyme activities [light blue symbols, including SOD (superoxide dismutase), CAT (catalase), POD (peroxidase)]; photosynthetic traits [orange symbols, including Pn (net photosynthetic rate), Tr (transpiration rate), St (stomatal conductance), WUE (water use efficiency)]; Na+, K+, K/Na (purple symbols); yield-related variables (dark blue symbols, including yield, SFW (shoot fresh weight), SDW (shoot dry weight), RFW (root fresh weight), RDW (root dry weight); NaCl (NaCl concentration, white symbol); TI (tolerance index, red symbol); GE (Gene expression, yellow symbol)
